Electronic program guide for obtaining past, current, and future programs

ABSTRACT

An electronic program guide (EPG) for facilitating obtaining copies of selected programs includes a plurality of program listings, the program listings including listings for previously broadcast programs available for downloading to a user&#39;s recording device, programs currently being broadcast available for downloading to the user&#39;s recording device, and programs which may be recorded on the user&#39;s recording device during a future broadcast of the programs. This EPG merges two models of distribution for broadcast content (e.g., EPGs) and video on demand (VOD) systems (e.g., video catalogs) to address the problem of acquiring a recording of a program that was broadcast in the past. The EPG of the present invention provides a combined, unified user interface whereby a user may easily obtain a copy of any one or more of past, current, or future programs.

BACKGROUND

This invention relates generally to electronic programming guides forfacilitating the selection, viewing, and recording of televisionprograms or other multimedia content.

Electronic programming guides (EPGs) typically display a two dimensional(2D) grid of television (TV) program times on one axis and televisionchannels or service providers on another axis. The EPG grid may includeitems for particular TV programs, movies, or other multimedia contentarranged by channel and time of presentation. The user can typicallyselect any of the programs displayed by the EPG for viewing orrecording. This is usually done by selecting a particular current orfuture program listing using a remote control device to cause theselected program to be automatically tuned for present viewing orscheduled for recording or subsequent (i.e., future) viewing. EPGstypically display limited information about a TV program. Theinformation is usually limited to the title of the program, the time itis broadcast, and the channel broadcasting the program. The informationis typically presented in a static text format, with the title residentin the grid slot associated with a particular time and channelcombination. One drawback of current EPGs is that they typically displaylistings only for programs either now being broadcast or programs thatwill be broadcast in the future.

Personal video recorders (PVRs) are becoming popular as a device used torecord programs currently being broadcast or that will be broadcast inthe near future. In this sense, they are much like well-known videocassette recorders (VCRs). However, PVRs utilize a hard drive to storethe programs in digital form, rather than in analog form on videotape asdo VCRs.

Video-on-demand (VOD) systems provide access to previously recordedprograms at specified, staggered times. VOD programs are commonlyprovided by cable TV companies and satellite networks for a fee (e.g.,they are usually pay-per-view (PPV) programs).

The user interface for each of these types of systems is very different.The PVR usually provides an EPG as a means for selecting programs, muchlike a set-top cable TV box or a set-top satellite receiver. Incontrast, a VOD system typically provides a catalog metaphor forordering programs. The catalog may list, at a minimum, the name of aprogram, a set of times when the program is to be broadcast, and anassociated viewing cost. Some VOD systems list available PPV programs inthe EPG used for subscription and/or free channels by the cable TVprovider or satellite provider.

Neither of the above-described systems allows for a user to easilyobtain a copy of a previously broadcast program. One traditional way toacquire a previously broadcast program is to call or write thebroadcaster or an affiliated entity to buy a videotape or digitalversatile disk (DVD) copy of the program. This involves the user takinga number of steps to get the program, such as finding the right contactinformation, placing a telephone call, writing a letter, or placing anelectronic order using a web browser on the Internet, and arranging forpayment and delivery. This is inconvenient to the user.

DETAILED DESCRIPTION

Embodiments of the present invention comprise an electronic programguide (EPG) that merges the two models of distribution for PVRs (e.g.,EPGs) and VOD systems (e.g., video catalogs) to address the problem ofacquiring a recording of a program that was broadcast in the past. TheEPG of the present invention provides a combined, unified user interfacewhereby a user may easily obtain a copy of any one or more of past,current, or future programs.

Reference in the specification to “one embodiment” or “an embodiment” ofthe present invention means that a particular feature, structure orcharacteristic described in connection with the embodiment is includedin at least one embodiment of the present invention. Thus, theappearances of the phrase “in one embodiment” appearing in variousplaces throughout the specification are not necessarily all referring tothe same embodiment.

Referring to FIG. 1, a sample portion of an EPG graphical user interfaceaccording to embodiments of the present invention may include a seriesof program times corresponding to a current time and date along one axisand a series of channels, TV service providers, or TV networks, alonganother axis. Thus, a plurality of listings of programs may be shownaccording to time and channel. Conventionally, the user may select agiven program for viewing or recording using a remote control device forany program listing being displayed that is currently being broadcast orwill be broadcast in the future. In one embodiment, the EPG display maybe in a 2D format (e.g., a conventional grid having time on one axis andchannels on another axis) having a plurality of data cells. In otherembodiments, the EPG display may be in a 3D format, where a thirddimension may be included to give the appearance of depth to theconventional 2D grid using known 3D computer graphics techniques.

Typical prior art EPGs only display listings for programs currentlybeing broadcast or that will be broadcast in the near future (usuallylater the same day). Current EPGs, however, do not display listings forpreviously broadcast programs. According to embodiments of the presentinvention, the EPG may display listings for programs previouslybroadcast. As shown in the example of FIG. 1, according to embodimentsof the present invention, this EPG displays listings for both previouslybroadcast programs as well as current (that is, in progress) and futureprograms. Embodiments of the present invention comprise a display andinput device that together provide an EPG user interface to allow a userto easily record a copy of a program that is being or will be broadcast,as well as to request a copy of a program that was broadcast previously,which may be available on-demand from a service provider or programsource.

As shown in FIG. 1, the EPG of embodiments of the present inventionlists past, current, and future broadcasts. There are at least threeviewing and recording scenarios that may be addressed by the presentinvention. First, a user may determine prior to the start of a broadcastthat he or she wants to record a selected program. For example, as shownin FIG. 1, suppose the user wants to record the movie to be broadcast onchannel number 105 from 9 pm to 11 pm. In this case, the user may use aremote control device to select the program listing shown in the EPG forthe upcoming program to be broadcast and to instruct a recording devicesuch as a PVR to record the program when it is broadcast, much as isdone conventionally. In one alternate embodiment of this scenario, theuser may request that someone else's PVR (e.g., a friend's PVR, a familymember's PVR, etc.) that has available disk space be set up to recordthe program, and then forward a copy of the program to the user's PVR.The communication with the other PVR may be according to any of severalwell-known communications means (e.g., infrared (IR), radio, telephone,e-mail, instant messaging (IM), and so on). When the program isbroadcast, usually at the scheduled time, the user's PVR may receive andrecord the program.

Secondly, a user may determine in the middle of a broadcast of aselected program that he or she wants a copy of the program. Forexample, suppose the user wants a copy of the news program currentlybeing broadcast on channel number 110. This program started at 8 pm andthe current time is somewhere between 8 pm and 9 pm (e.g., 8:20 pm).However, the user missed the opportunity to request the recording of theprogram being shown on channel number 110 starting at 8 pm prior to thestart of the program. Perhaps the user just turned the TV on at 8:10 pm,watched the program for a few minutes, and then determined that theprogram was something he or she wanted a copy of to show to a familymember or friend. Alternatively, perhaps the user watched the programfrom the beginning, but then decided during the program that he or shewould like a copy of the program. Normally, the user would not be ableto recover the missed portion of program being broadcast.Conventionally, the user could start recording using a VCR or PVR at thecurrent time and obtain the rest of the program, but the beginning wouldbe missed. Alternatively, the user could use conventional means to buythe entire program through another sales mechanism (telephone, mail,web, etc.), but this is inconvenient for the user.

With embodiments of the present invention, in this second scenario theuser may simply select the program listing in the EPG for the programbeing broadcast and watched, select an “obtain program copy” inputbutton displayed by the EPG (perhaps in a “pop-up” window)(not shown inFIG. 1) or via another selection mechanism (e.g., a special button onthe remote control device for this purpose), and a copy of the programmay be communicated from a program source to the user's recordingdevice, such as a PVR, personal computer system (PC), home networkserver, or other electronic device. A program source may be, forexample, a broadcasting network, a cable TV or satellite TV provider, aproduction company, a content distribution entity, or other distributorof programs. The communication of the program to the user's recordingdevice (e.g., PVR, PC, home network server, or other electronic device)may be accomplished by any means, including, for example, a computernetwork such as the Internet, a wireless network, and a cable TV orsatellite TV network.

Although the program is in the middle of being broadcast, the programsource may archive the program in digital form and have the programavailable for transmission to a user's recording device upon request.Alternatively, the program source may already have the program availablefor distribution to a requesting user prior to broadcast of the program.In one embodiment, the transmission of the program may be performed inreturn for a fee paid by the user. In another embodiment, the programmay be obtained from another PVR that may have the program storedthereon. This second PVR may have recorded the program while the programwas broadcast or may have obtained a copy of the program prior to orsubsequent to the broadcast of the program. In this mechanism, a peer topeer (P2P) network of PVRs may be employed.

Thirdly, a user may determine after a program is over that the userwould like a copy of the program. Perhaps the user didn't make it homein time to program the user's PVR or VCR prior to the start of theprogram, or the user learns from a friend or family member after theprogram was broadcast (e.g., later the same day or on a different,subsequent day) that the program was entertaining and worth obtaining acopy. With embodiments of the present invention, the user may simplyselect the program listing in the EPG for the desired previouslybroadcast program, select an “obtain program copy” input buttondisplayed by the EPG (perhaps in a “pop-up” window)(not shown in FIG. 1)or via another selection mechanism (such as a special button on theremote control device for this purpose), and a copy of the previouslybroadcast program may be communicated from a program source to theuser's PVR, computer system, or other electronic device via any of thecommunications means discussed above. This communication of the programcopy may occur immediately after the user's selection or may beperformed at a specified later point in time (e.g., in the late eveningor middle of the night when more bandwidth or processing power may beavailable).

For example, as shown in FIG. 1, suppose that the user desires a copy ofthe documentary that was previously broadcast from 5 pm to 7 pm onchannel number 115. The user may use a remote control device to selectthe program listing in the EPG for this program and directly order acopy of the program to be delivered to the user's recording device(e.g., a PVR, PC, and the like). In one embodiment, the user's PVR maybe coupled over a network to communicate with the program source toobtain the requested program. In this case, the PVR receives therequested program over the communications network and stores the programfor future use.

As noted, in current EPGs, the user interface (and possibly also therecording device) required to order a program on-demand is completelyseparate from the user interface to record a program that will bebroadcast. If a user discovers, one day after the program's broadcast,that he or she wanted to record it, the user may be required to use anon-demand interface to search a catalog of programs for the desiredprogram. With embodiments of the present invention, a unified userinterface for an EPG may be provided which combines the capabilities ofobtaining copies of previously broadcast programs and recording ofprograms to be broadcast in the future. No distinction is made in theuser interface of the EPG between past programs, current programs, andfuture programs, or between video-on-demand or normal broadcastprograms. Thus, the interface may be easier to use by to view programsand to obtain copies of selected programs. As noted, in one embodiment,any program copies obtained may be stored on a user's PVR for futureviewing.

FIG. 2 is a flow chart of a process of providing an enhanced programlisting in an EPG in accordance with an embodiment of the presentinvention. At block 20, the EPG may collect or otherwise obtaininformation regarding past, current and future programs. Data collectionmay be performed as needed by the EPG or based on a periodic schedule.The information collected may comprise information such as title,length, rating, main actors and actresses, category, and so on. At block22, the EPG may display one or more program listings based on theinformation collected at block 20. The program listings displayed to theuser may include previously broadcast programs (i.e., past programs),currently broadcast programs (i.e., current, in-progress programs) andprograms to be broadcast in the future (i.e., future programs). At block24, the user may select any program listing displayed by the EPG. Theuser may select a program listing corresponding to a program of whichthe user would like to obtain a copy. In one embodiment, the copy may bein digital form as recorded onto a storage medium such as a hard disk ofa PVR. In one embodiment of the invention, the user may use conventionalmeans for selecting input choices in an EPG, such as a remote controldevice. The remote control device may be used to highlight a desiredprogram listing and select an “obtain copy” function. In one embodimentthe “obtain copy” function may be represented by a button on the remotecontrol device.

At block 26, the EPG accepts the user's request to obtain a copy of thedesired program represented by the selected program listing. At block28, if the selected program is a program to be broadcast in the future,the user's recording device (e.g., a PVR, PC, VCR, home network server,or other electronic device) may be set up to record the program as it isbroadcast. At block 30, if the selected program is a program that iscurrently being broadcast, has previously been broadcast, or is aprogram available for download without being broadcast (e.g., in thelibrary of available programs from a program source), a request may besent to a source of the program and, in response to the user's request,the program may be communicated from the program source to the user'srecording device.

In various embodiments of the present invention, different indicatorsmay be shown by the EPG in program listings to represent additionalinformation relating to the program. For example, if a programrepresented by a program listing in the EPG is available for downloadupon request to a user's recording device, the color of the programlisting cell in the EPG and/or text may be set to a first color (e.g.,green). If a program is unavailable for downloading, the color of theprogram listing cell in the EPG and/or text may be set to a second color(e.g., red or gray). If a program is unavailable due to copyrightrestrictions, the color of the program listing cell may be set to athird color (e.g., black). In another example, programs available fordownload may be displayed brightly, while unavailable programs may bedisplayed in a dimmed manner. Alternatively, the colors used foravailable programs may be an indicator of the cost to the user ofdownloading the program. In other embodiments, program listings mayinclude information, symbols and/or icons to indicate the image qualityof the program that is available for download, copyright informationregarding the program (possibly including prohibitions againstretransmission of the program), a copy count or copy permissions,bandwidth of the connection required to download the program, parentalcontrols, and other control information.

In one embodiment, rather than downloading the selected past or currentprogram to the user's recording device, the past or current program maybe sent to the user by mail on a physical medium such as a videotape orDVD. In this case, the user interface of the present invention may stillbe used to easily and conveniently select the program of which the userdesires a copy. The user may use the remote control device to select andpurchase a previously broadcast program, current program, or otheravailable program as displayed by the EPG, and the present EPG respondsto the user's selection by processing the order for fulfillment by aprogram source or other entity.

Referring to FIG. 3, in accordance with one embodiment of the presentinvention, software implementing the improved EPG of the presentinvention may be stored in and executed by a set-top box 42 that restsatop or near a television receiver 41 having a display screen 52. Inother embodiments, a personal computer (PC), home network server, orother processing system may used in place of the set-top box. A remotecontrol unit 44 may control the television receiver 41, through itsinterface 48, and the set-top box 42, through its interface 46. Theinterfaces 50, 48 and 46 may be wireless interfaces, such as infraredinterfaces in accordance with one embodiment of the present invention.Although a TV is shown in FIG. 3 as the display device, other displayssuch as computer monitors may also be used.

A plurality of highlight navigation keys 45 and a select key 47 may beprovided on the remote control unit 44 for selection of the variousicons, user interface buttons, and program listings displayed by theEPG. Particularly, the navigation keys 45 may be utilized to move thehighlighting of a program listing to the desired grid entry of the EPGfor the desired program that may be selected using the select button 47.An “obtain copy” button 51 may also be included in the remote controlunit to facilitate easy and convenient purchase and/or ordering of aselected program highlighted in the EPG.

Set-top box 46 receives programs from a program source 54. Communicationof the programs from the program source to the set-top box may be by anyknown means for receiving TV and multimedia programming, includingcables, satellites, antennas, computer networks, the Internet, and soon. In one embodiment, the set-top box executes the EPG software and, asa result of user interaction with the EPG of the present invention,instructs PVR 56 and/or VCR 58 to record a program to be broadcast.Additionally, the set-top box may, as a result of user interaction withthe EPG of the present invention, instruct the PVR to obtain a copy of adesired program from the program source or another source.

Although a particular arrangement of devices is shown in FIG. 3, it willbe understood by those skilled in the art that other arrangements arealso possible. For example, the functionality of one or more of theset-top box, PVR, VCR, TV and/or monitor may be combined into onedevice. In one embodiment, the functionality of one or more of theset-top box and PVR may be combined into a home server, computer system,or home entertainment electronics device. Generally, the PVR maycommunicate with the program source to obtain programs using anyavailable communication mechanism.

Referring to FIG. 4, the device used to provide the functionality of oneor more of the set-top box 42 and PVR 56 to implement the EPG ofembodiments of the present invention may include a processor 74 coupledto a bridge 66. The bridge 66 may couple a graphics accelerator card 70and a system memory 68. The graphics accelerator card 70 may be coupledto the display or television receiver 41 in one embodiment of thepresent invention.

The bridge 66 may also couple to a bus 74 that may couple to atelevision tuner/capture card 76. The card 76 may be coupled to a videosource such as a cable or satellite receiver as two examples, althoughthe invention is not limited in this respect. The card 76 may includeany circuitry and/or programming to receive programs from a programsource. In other embodiments, the programs may be received via a networkinterface card coupled to the bus. The bus 74 may also be coupled to abridge 78. The bridge 78 may be coupled to a hard disk drive (HDD) 80that stores software 30 implementing the improved EPG embodied in thepresent invention.

The bridge 78 may also be coupled to a bus 84. The bus 84 couples aserial input/output (SIO) device 86 and a basic input/output system(BIOS) storage 92. The SIO device 86 in turn may be coupled to theinterface 87 that communicates with the remote control unit 44.Particularly, the remote control unit 44 may include it's own interface50 coupled to a controller 88. The controller 88 receives input commandsfrom a keyboard or keypad 90.

The techniques described herein are not limited to any particularhardware or software configuration; they may find applicability in anycomputing or processing environment. The techniques may be implementedin hardware, software, or a combination of the two. The techniques maybe implemented in programs executing on programmable machines such asmobile or stationary computers, set-top boxes, personal digitalassistants, and similar devices that each include a processor, a storagemedium readable by the processor (including volatile and non-volatilememory and/or storage elements), at least one input device, and one ormore output devices. Program code is applied to the data entered usingthe input device to perform the functions described and to generateoutput information. The output information may be applied to one or moreoutput devices.

Each program may be implemented in a high level procedural or objectoriented programming language to communicate with a processing system.However, programs may be implemented in assembly or machine language, ifdesired. In any case, the language may be compiled or interpreted.

Each such program may be stored on a storage medium or device, e.g.,compact read only memory (CD-ROM), digital versatile disk (DVD), harddisk, magnetic disk, or similar medium or device, that is readable by ageneral or special purpose programmable machine for configuring andoperating the machine when the storage medium or device is read by thecomputer to perform the procedures described herein. The system may alsobe considered to be implemented as a machine-readable storage medium,configured with a program, where the storage medium so configured causesa machine to operate in a specific manner.
